Earthworm Joe is a great game that emulates the look and feel of the classic Nintendo game and watch series from the 80's. This is a near perfect emulation of an LCD screen, and although it might seem a step in the wrong direction to be marveling about a High Def display imitating a grey and black LCD, there is absolutely a certain charm about it.
The game play is as simple as it comes. You can move your character (a worm) left and right, as you try to make it to the other side of the screen without getting swooped by birds. As expected, the game play becomes more difficult as your score increases.
If you want to feel some nostalgia and experience, then check out Earthworm How,
In the words of the developers:
This game is an emulation of handheld LCD games from the 80s, but this is a new game based on those existing games, developed to look and feel like those retro classics. The story is about an earthworm, who wants to visit his neighbour, but angry birds try to catch him on the fields.
